Abstract
THIS book is edited from a course of lectures given at the Sorbonne. The first part deals with the kinematics of rigid bodies in two and in three dimensions, including the theories of roulettes, of acceleration centres and of relative motion; and concludes with a chapter on simple mechanisms. These are all well-worn topics, and afford little opportunity for novelty of treatment. In the few pages devoted to finite rotations we notice, however, an elegant method of investigating Rodrigues's formulæ which is, at all events, not current in this country. The exposition is marked throughout by the author's usual facility, and the illustrations are well chosen. A severe taste might perhaps take exception to the way in which analysis and geometry are continually mixed up in the proofs, but a course of lectures intended primarily for a special class of students is not to be judged by the same canons as a formal treatise.
